This is something I worked on a while ago, but it seemed appropriate with Jurassic Park: 3D being released this week. This is a mockup of a poster for a fourth Jurassic Park movie, which I created while I was entertaining the idea of writing a JP fan film (the idea hasn't completely dissipated, by the by). The byline is "Las Cinco Muertes", or "The Five Deaths", which was the eerily appropriate local name for the chain of islands that John Hammond bought up in the novels by Michael Crichton.
The logo and poster are entirely made in Photoshop. The credit text is the only thing I skipped out on: It's "borrowed" from the poster for the first Jurassic Park.
Enjoy! And if you're Steven Spielberg, Universal or Amblin Entertainment, don't be offended, it's just an image. If I've stolen your idea, then damn -- I'm better at this than I thought I was.
